I have a pretty old Gateway FPD1520 that blows fuses on the inverter board. I think I have it troubleshot down to a shorted power transistor with part number D1864. The board has 2 of them, I took them both out and they ohmed out differently so I suspect one of them is bad.
3 questions:
1) What is the best way to ohm out a D1864 power transistor
2) What is a good cross to something Digikey has? I see too much confusion, but I think it's a 2SD1864TV2Q
3) I noticed a letter on the back of the chip - one of them is stamped "J" and the other is stamped "A". what does this mean?
Thanks!
